We're doing some code cleanup, fixing signed/unsigned comparisons, running static analysis, etc, on the code base of C, C++, and Java.
One of the warnings we're getting is
warning: ISO C does not permit named variadic macros
And its companion warning
warning: ISO C99 requires rest arguments to be used
Now, in the C code I used the C99 standard variadic macro to fix the problem, but in the C++ code, what is the correct answer? Using the same C99 style results in a different warning
warning: anonymous variadic macros were introduced in C99
For which I don't see any answers.
We're using GCC (G++) 4.4.3 in Linux.
I'm hoping there is some flag, or other method that can correct, or disable it for the specific section of code - but its for the logging which is used in almost every file...
Use the gcc option -Wno-variadic-macros
to disable that particular warning.
Edit: (from comments)
To disable the warning for a section of code but leave it on in general, use #pragma GCC diagnostic
described here.
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wvariadic-macros"
// Your code and/or include files
// (No variadic warnings here)
#pragma GCC diagnostic pop
